National Space Institute (NSI)

The National Space Institute (NSI) was an organization founded by officers of the National Space Club to maintain public support for the United States space program; its first president was Wernher von Braun. The NSI was initially incorporated as the National Space Association in June 1974, but was renamed in April 1975. In April 1987, the NSI merged with the L5 Society to form the National Space Society.
